ABSTRACT
BACKGROUND: This study assessed the psychometric properties of the 10-item Connor Davidson Resilience Scale (CD-RISC-10), a self-report measure of resilience, in youth receiving treatment and/or screening positive for depression/suicidality in psychiatric outpatient settings.
METHODS: Data from 908 youth (age 12-20 years) were analyzed. A confirmatory factor analysis (CFA) model was fit to the data, and goodness-of-fit was assessed using indices such as the comparative fit index (CFI). Psychometric analyses were performed through the lenses of classical test theory (CTT) and item response theory (IRT). Measurement invariance of the scale was assessed by classifying the sample by depression severity. Finally, intraclass correlation coefficients (ICC) from test-retest were used to assess the reliability of the scale using data collected at baseline and one-month post-baseline.
RESULTS: The scale was unidimensional, representing a single latent trait. CFA demonstrated acceptable model fit (CFI = 0.94). CTT analyses showed good internal consistency (Cronbach’s alpha 0.85) and good item discrimination (item-total correlations between 0.38 and 0.66). The scale demonstrated good test-retest reliability over a one-month period (ICC = 0.82). IRT analyses exhibited good item performance on all but the three items related to versatility, humor and persistence. These items were also deterrent to the scale having full scalar invariance.
LIMITATIONS: Limitations include questionable generalizability beyond the sample and biases inherent in self-report scales.
CONCLUSIONS: CD-RISC-10 has acceptable reliability and validity. However, depressive symptom severity affected selected item performance. If these findings are confirmed in other independent samples, a seven-item version of the scale may be investigated for depressed samples.
